Battery Draw Amperage

Is the glove box light on the same circuit? How about the under hood light? I forget off hand. On one of my past 200s, just moving the trunk wires around cured the problem. 

Bob's method is MUCH safer than hoping your partner will actually open the trunk after you climb in and close it :-)

 Agree with Tony. #4 is the trunk light, vanity mirror lights, etc. Take your digital camera, turn the flash off, put it on timer, throw it in the trunk pointed at the light, close the lid and see if you get a picture. I had the same issue years ago and it was the trunk light.

As Dewitt said, that is too much, as it is about a small light bulb

draw. That is the perfiect amount (.2a, or 200ma) to drain the battery

in 4-5 days. Whatever is on that #4 fuse is right where I'd be

looking. And, yes, it is charging just fine.
